Accounting Journal Entries: The Basics Explained

Accounting Journal Entries: What They Are, How They Work, and Why They Matter

Every transaction you make, from buying coffee to paying payroll, tells the financial story of your business.

To get that story right, you need to record each transaction correctly in a journal entry, which will then post to the general ledger—your business’s central nervous system of financial data. An accurate general ledger provides the details to produce accurate financial statements (e.g., balance sheets, income statements, cash flow statements), which are essential for making informed decisions and remaining compliant.

Today, we’ll look at what goes into a journal entry, how to format one, and what common examples look like in practice, so you can keep audit-ready books.

What Are Accounting Journal Entries, and What Information Belongs in Them?

An accounting journal entry is a formal record of a business transaction, showing which accounts have been debited or credited. In business accounting, debit is money coming in, and credit is money going out. And, as BILL explains, the five main business account types are assets, liabilities, equity, revenue, and expenses. Debits increase assets and expenses and credits increase liability, equity, and revenue. These debits and credits are the basis for double-entry accounting.

According to Harold Averkamp of AccountingCoach, “Double-entry bookkeeping refers to the 500-year-old system in which each financial transaction of a company is recorded with an entry into at least two of its general ledger accounts. At least one account will have an amount entered as a debit and at least one account will have an amount entered as a credit. Further, the total amounts entered as debits must be equal to the total amounts entered as credits. Meeting these requirements will result in the accounting or bookkeeping equation being in balance at all times.”

When creating journal entries, business transactions should be listed in chronological order and include essential details like:

• Transaction date.
• Debit and credit amount.
• Accounts affected.
• A reference number.
• A short description of the transaction.

Here’s an example. Let’s say you run a bakery, and you paid $200 cash in early February 2026 for Valentine’s Day themed sprinkles. Your journal entry would include (in addition to a reference number):

• Transaction date: February 3, 2026.
• Debit and credit amount: $200.
• Accounts affected: Expenses ($200 debit) and Cash ($200 credit).
• Description: Sprinkles for Valentine’s Day 2026.

What Is an Accounting Journal, and How Does It Differ from the General Ledger?

An accounting journal, often known as “the book of original entry,” is the initial chronological record of all your business transactions. Accounting journal entries are raw data. They just show—accurately and sequentially—how you’re spending your business’s money. The accounting journal provides the information you need to understand your financial activity and is a critical part of your audit trail.

The general ledger takes the information from the accounting journal, organizes it, and ensures the values are debited and credited to the proper account categories, so account balances can be calculated. These account balances are then moved from the general ledger to the trial balance before your financial statements are finalized.

Together, the accounting journal and the general ledger provide the information you need to create accurate financial statements and reports.

Best Practices for Accuracy

Before your journal entry gets posted to the general ledger, there are a few things you can do to manually make sure the information is correct:

• Confirm that the debit and credit totals are equal.
• Make sure all entries are in chronological order.
• Correct any period or date errors.
• Ensure the description is clear and concise.
• Support the journal entry with valid sources.
• Verify that the appropriate affected accounts are noted.
• Be consistent in naming and referencing.

You’ll also want to attach important documentation, such as invoices and receipts, to your accounting journal entries, so the accuracy of each transaction can be verified by cross-referencing documents. And you’ll need regular reconciliation processes to catch potential errors, which can include but are not limited to:

• Unbalanced entries.
• Incorrect accounts.
• Incorrect dates or accounting periods.
• Weak descriptions.
• Duplicate entries.
• Reversal or adjustment confusion.

Another best practice for journal entries? Automating these processes by implementing a modern enterprise resource planning (ERP) solution with integrated accounting applications. Doing so will empower you to more easily manage, streamline, and automate your accounting journal and general ledger workflows—boosting efficiency, accuracy, and auditability.

Summary: The Minimum You Need for Reliable Journal Entries

Accounting journal entries are the first step to building a fact-based, reliable financial history for your business. Your ability to pass audits and make strategic decisions is based on ensuring each journal entry is recorded correctly and undergoes a thorough review and proper approval.

These processes can be complicated, especially as your business grows in size and complexity. Manually inputting and tracking multiple journal entries is inefficient and increases your chances of making mistakes.
